The Premise of Assuring Rendering Efficiency: Testing First Before Rendering

Although Superman: Man of Steal has been on the downside for some time, it not only continually follows the production of classic sci-fi movies, but also made the audience have an indelible impression on its unique and special effects. In the meantime, this movie also initiates lots of unique lenses and technology for sci-fi movies, which is also worthy of learning and respecting by render farms with considerable render nodes in rendering technology.

Superman: Man of Steal started at the “Krypton”, which was unstable nucleus and going to destroy this star. Weta Workshop created the environment in the planet, the character of creatures and the key factor of showing vision, which was called “liquid geo” by movie producers. “Basically, it’s a bunch of silver beads that were suspended through a magnetic field, and the machine was able to control that magnetic field so that the collection of beads behave almost like three-dimensional pixels,” said Weta’s visual-effects supervisor Dan Lemmon. This liquid geometry device appeared in the scene of "Krypton" and the subsequent emergence of the spacecraft.

In order to create this liquid geometry, Weta Workshop had taken the following steps:

1, Visual style: looking carefully at these silver beads, we would find cones with tiny angle, which would be composed of surface of presented objects in a variety of consoles. Weta arranged the dominant surface of the cones together in accordance with the direction of the normal by using the surface normals and the combination of simulation.
2, Modeling and animation: The animation production of relief contained both the pattern of the face and other parts of Laura and also the background pattern of the surveillance ship. “We had to develop a pipeline to bring in assets, so instead of going through the route of reducing the polygon count to something usable what we would then do-you would take the model in whatever way it was made and just scatter discrete points onto it, and extract the matrix onto the animation and copy these points onto the matris and have these sparse points behaving in a way that the model would.” We had animation provide us with geometry that we would then track beads on. Those beads would then be turned active in front of the actual console and the console would decide what beads it needed to provide to actually draw particles from the actual earth we described or this invisible bowl.

3, Lighting and rendering: Weta used the next generation of RenderMan, because they made the full use of the ray tracing technology after the improvement and instantiate the object. Motion blur was also a challenge and Weta has the traditional motion blur, photons can move through technology. To achieve this, they also made rendering test through a variety of programs to get the most realistic rendering effects. Rendering is not easy, parameter settings, the prevailing environment of the network and other factors that will affect the rendering, so it is the prerequisite of fast completion of the rendering to promote test first, no matter for individual rendering or rendering companies. Fox Renderfarm is one of the leading online rendering service providers, which also includes blender render farm, maya render farm, good render farm software, vray render farm and 3ds max render farm, that is to say we are in supportive in the plug-ins like these.
